Question: Diffucukty with display

restart;
with(geometry):
with(plots):
_EnvHorizontalName = 'x':
_EnvVerticalName = 'y':
point(A, [-2, 7]):
point(B, [-5, -2]):
point(C, [8, -2]):
triangle(ABC, [A, B, C]):
display([draw[A(color = black, symbol = solidcircle, symbolsize = 6), 
               B(color = black, symbol = solidcircle, symbolsize = 6), 
               C(color = black, symbol = solidcircle, symbolsize = 6), 
               ABC(color = blue)], 
         textplot([[coordinates(A)[], "A"], 
              [coordinates(B)[], "B"], 
              [coordinates(C)[], "C"]],
              align = [above, right])], 
              axes = none);
Would you explain to me why this error ? Thank you.
Error, (in plots:-display) expecting plot structures but received: [geometry:-draw[A(color = black, symbol = solidcircle, symbolsize = 6), B(color = black, symbol = solidcircle, symbolsize = 6), C(color = black, symbol = solidcircle, symbolsize = 6), ABC(color = blue)]]
